Created Open Directory Master, can’t log in with network accounts?

Hi everyone, I created an Open Directory master. DNS is running on the server, I can do a forward and reverse lookup and all that fun stuff. I created 2 network accounts and am able to successfully bind a computer to the directory. It shows up in Authentication and contacts in Directory Services. There is a separate server that controls DNS, and this server (Open Directory master) doesn't control any zones, doesn't do zone transfers. Doesn't do much of anything with DNS - I just want it to be able to point to itself. However I am unable to unbind the computer - it says that it can't contact the LDAP server, would I like to force this action? Also network accounts are unavailable on the (so far) two machines I've bound. The OD master is on a different subnet from the clients machines. I don't think that should have any impact though... HELP!
